| Physical and Chemical Properties | Bioactive necrsulfonamide is a specific and potent inhibitor of cell necrosis that exerts its effects by inhibiting MLKL. |
| Use | (E)-Necrosulfonamide is an inhibitor of necroptosis. Blocks mixed lineage kinase domain-like protein (MLKL), a critical substrate of receptor-interacting serine-threonine kinase 3 (RIP3) during necrosis. Prevents MLKL-RIP1-RIP3 necrosome complex from interacting with downstream necrosis effectors. Binds and inhibits gasdermin D. Inhibits pyroptosis. |
| Target | necrosis(MLKL) |
| In vitro study | Necrsulfonamide inhibits MLKL-mediated necrosis by preventing the function of the N-terminal CC region of MLKL. It inhibits necrosis downstream of RIP3 activation. Necrsulfonamide did not have any effect on TNF-α and Smac mimetic-induced apoptosis in Panc-1 cells that did not express RIP3, even at concentrations up to 5 μm. Necrsulfonamide is effective in inhibiting necrosis in human cells, but not in mouse cells. The species-specificity of necrsulfonamide may be due to the dependence of necrsulfonamide binding on the 86th cysteine of human MLKL, which is replaced by tryptophan in mouse MLKL. |

Necrosulfonamide - Cell Experiment
Cell lines: HT-29 cellsConcentrations: 1 μMIncubation Time: 8 or 12 hrsMethod: Necrosis inhibitors induce diverse effects on MLKL phosphorylation. HT-29 cells are treated with T/S/Z with or without necrosis inhibitors for 12 hr or 8 hr. The number of dead cells is determined by measuring released protease activity in culture medium. The whole-cell extracts are prepared and analyzed by western blotting. The final concentrations of 10 μM necrostatin-1 or 1 μM necrosulfonamide are used to block necrosis.
